A method of retrieving desired information from information which is continuous over time, the method comprising the steps of:

• defining, as a plurality of information units, portion information which is continuous over time which forms the information which is continuous over time;
• extracting a predetermined feature amount for each information unit;
• arranging in order the respective information units on the basis of the feature amounts of the respective information units;
• generating, for each information unit, a visualized index image on the basis of the feature amount, and for arranging-outputting the index information on the basis of the ordering by the sorting step;
• and
• playing back at least the information units on the basis of an instruction for playback processing of information units corresponding to the index images.
